Evaluation of axial dispersion flow parameters in trickle bed reactor (TBR) is presented in this contribution. Four axial dispersion models were employed to identify principal flow parameters (mean residence time, Peclet number and transport delay) from experimental data. The impulse-response method was employed to measure the residence time distribution (RTD) in the liquid phase. Isobutanol was chosen as a suitable tracer for the selected liquid phase represented by toluene. Tracer concentration at the outlet from the reactor was continuously monitored by a digital refractometer. Optimal model and the best predictions of the parameters were obtained via non-linear regression and least square method.
